10 Claims.
it becomes necessary to add drill pipe sectionsor to withdraw the drilling string from the borehole.
In accomplishing this and other objects of the invention, as hereinafter pointed out, I have provided improved details of structure, the preferred form of which is illustrated in the accompanying drawings, wherein:

Fig. 6 is a detail section on the line 6-6 of Fig. 2. p
Referring more in detail to the drawings:
l designates the rear portion of a drilling rig such as used in drilling shallow wells, the taking of cores, drilling of shot-holes, and performing similar oil field operations. The drilling rig illustrated is of portable character and is mounted upon a platform 2 carried upon the frame 3 of a motor vehicle 4. supp rted on the platform 2 is the usual mast 5, winding drum 6, and other appliances necessary in drilling a bore-hole. Mounted at the rear of the platform is a drill rod rotating mechanism 1, and a drill rod feeding mechanism 8. 'v v The parts above mentioned may'be of any conventional construction, but in the drawings, the drill rotating mechanism is shown as comprising a cylindrical housing 9 in which is rotatably mounted a Kelly rod drive bushing Ill, and which is driven from the power plant of the motor vehicle'through suitable gearing as in conventional practice.
Extending laterally of the housing 9 are winglike arms II and 12 carrying hydraulic cylinders l3 and H of the feeding mechanism 8. Slidable in the cylinders are the usual pistons (not shown) to which are secured rods l5 and I6, having their upper ends connected by a yoke ll. The yoke ll includes a. rearwardly curved, off-set portion l8, intermediate the cylinders, so that the yoke clears the Kelly rod opening IQ of the bushing l0, and allows ample clearance for pulling and running in sections of drill pipe when the Kelly rod 20 is removed therefrom as later described.
Formed at the ends of the yoke are ears 2i and 22, to which are connected guide rods 23 and 24 located in parallel relation with the piston rods [5 and i5 and having sliding hearing within tubular guides 25 and 26 carried by the wings I! and I2. Formed on the opposite side of the yoke are pairs of spaced flanges 21-28 and 29-30, having registering openings 3| therethrough to .pivotally secure a. Kelly rod chuck carrier and connecting member 32, as now to be described.
The Kelly rod connecting member is of substantially bar shape, and has its central portion provided with a ring-like housing 33, carrying antifriction bearings 34 and 35 therein to journal a sleeve-like spindle 36 of a chuck 31. The spindle 36 has an axial bore 38 adapted to align with the bore I 9 of the drive bushing and wherethrough the Kelly rod 20 is passed when it is connected to the drilling string. The chuck 31 may be of any conventional design but is here shown as including sets of jaws 39 adapted to' grippingly engage the Kelly rod upon adjustment of the screws 40 and whereby the Kelly rod is adapted to be raised or lowered responsive to actuation of the pistons in the respective hydraulic cylinders so that pressure may be applied on the drilling string to promote cutting operation of the bit, or relieved therefrom when the weight of the'drilling string is excessive for favorable drilling operation.
Extending laterally from the sides of the ringlike housing are arms "-42, having sleeve por= tions 43 and 44 at the ends thereof. The sleeve portions are providedwith bores 45 adapted to register with the openings 3| previously mentioned. The sleeve-like portions are such as to fit snugly between the ears 21-28 and 29-30 to form hinge joints whereon the bar-like member is adapted to swing as later described, and whereby it is retained in fixed relation with the connecting yoke H. The shape of the arms and the location of the hinge connections are such that the bore of the chuck spindle axially aligns with the opening in the drive bushing so that when the drilling string is made up, the Kelly rod 20 is adapted to be freely passed therethrough as shown in Fig. 1, the connecting member being retained by hinge pintles, such as headed pins ll and II, extending through the respective openswivel head 49 suspended from the top of the mast by tackle as indicated by the balls 50, Fig. 1. At the start of drilling, the lower end of the Kelly rod is engaged within the drive bushing so that it is adapted to be rotated thereby. The pistons 01' the hydraulic cylinders are in the upper ends of the cylinders and the chuck is grippingly engaged with the Kelly rod.
When a pressure medium is admitted to the upper ends of the respective cylinders the pistons are moved downwardly to apply pressure on the drilling string through the connecting member 39 and chuck 36 which is carried thereby. When the pistons reach the bottom of the cylinders, the chuck is loosened from the Kelly rod and the pistons are raised by admitting pressure medium to the bottom of the cylinders'to carry the chuck upwardly to a new position with respect to the Kelly rod. Upon retightening of the chuck and again admitting pressure medium to the upper ends of the cylinders, the drilling pressure is reapplied to the drilling string whileit is drilling string, the Kelly rod being secured to a being rotated. This operation is repeated until;
the swivel approaches the rotating mechanism, whereupon it becomes necessary to apply another stand of drill pipe to the drilling string in the bore-hole. The chuck 36 is then loosened from gripping engagement with the Kelly rod, and the Kelly rod raised to the point where the lower end thereof passes above the top of the bore-hole. The pipe section connected therewith is then supported by a suitable spider or the like (not shown), while the Kelly rod is disconnected therefrom. While this operation is being performed, the-yoke and connecting member of the drill feeding mechanism are preferably raised to their uppermost position, as shown in Fig 5. When the Kelly rod is disconnected, it is raised freely through the chuck so that the lower end clears the drive bushing, whereupon one of the pintles 41 or 48 is removed and the connecting member 32 carrying the Kelly rod therewith is swung outwardly and away from the connecting yoke and to the side of the drilling and feeding mechanisms, as shown in Fig. 5. When in an out-of-the-way position, the Kelly rod may then be lowered through the chuck so the lower end thereof rests upon the ground, while the upper portion is supported by the connecting member. Another stand of drill pipe may then be readily lowered through the rotating mechanism, and connected with the upper end of the drilling string which is being supported by the spider, in a manner well known to those skilled in drilling, operations. After the drilling string has been lowered so that the bit again engages the bottom of the borehole, the Kelly rod is raised within the chuck and the connecting member still carrying the Kelly rod is swung to drilling position alongside the connecting yoke, whereupon the pintle is reinserted to securely lock the connecting member to the yoke. The Kelly rod is then lowered through the drive bushing and again connected with the upper end of thedrilling string. ,The chuck is again tightened so that the drilling operations may continue.
From the foregoing it is obvious that I have provided a simple and readily operablearrangement for handling the Kelly rod during running in or pulling out of the drilling string, and this is effected without providing'other complicated mechanism for removing the rotating and feeding mechanisms out of position as usually is the case in drilling rigs of this character.
